Bigrams and BiLSTMs Two Neural Networks for Sequential Metaphor Detection

WS 2018 Yuri BizzoniMehdi Ghanimifard

We present and compare two alternative deep neural architectures to perform word-level metaphor detection on text: a bi-LSTM model and a new structure based on recursive feed-forward concatenation of the input. We discuss different versions of such models and the effect that input manipulation - specifically, reducing the length of sentences and introducing concreteness scores for words - have on their performance...
